This calibration service is intended for customers who want improved performance from a properly running stock engine while retaining the existing ECM.\u003c\/p\u003e\n\u003cp\u003eWhipple engineers developed this calibration to increase the engine's available power by adjusting key calibration areas including RPM limit, spark advance, and fuel curve. By optimizing the spark curve for 91 octane or better fuel, the calibration is listed to add up to 25 HP over stock while maintaining stock reliability when used on the proper application with the correct fuel and setup.\u003c\/p\u003e\n\u003cp\u003eThe recalibration also raises the RPM limit from the stock 5400 RPM to 5800 RPM, giving customers additional prop selection flexibility. Whipple can also support many custom calibrations for built or highly modified engines when the complete engine combination and calibration requirements are provided.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Features\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eECM calibration upgrade for compatible Mercury Racing 500 HP EFI applications\u003c\/li\u003e\n  \u003cli\u003eDesigned for stock 500 HP EFI engine packages\u003c\/li\u003e\n  \u003cli\u003eOptimized for 91 octane or better fuel\u003c\/li\u003e\n  \u003cli\u003eIncreased RPM limit\u003c\/li\u003e\n  \u003cli\u003eIncreased spark advance\u003c\/li\u003e\n  \u003cli\u003eModified fuel curve for improved performance\u003c\/li\u003e\n  \u003cli\u003e5800 RPM limit compared to the stock 5400 RPM limit\u003c\/li\u003e\n  \u003cli\u003eListed gain of up to 25 HP over stock\u003c\/li\u003e\n  \u003cli\u003eMay help improve throttle response and reduce transom soot when the engine and fuel system are operating properly\u003c\/li\u003e\n  \u003cli\u003eCustom calibration support may be available for built or modified engine combinations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Service Process\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe stock ECM must be removed and shipped to Whipple Superchargers for recalibration service.
